I'm just trying to measure various cooling options in my new case, and thus attempting to fix variables.
However, I can see the 'package power' jumping suddenly from 75W to 125W a full *six minutes* after the system has been running at 100% load (with Prime65), the fan fixed at 100%, and the frequency fixed at 3650 in Ryzen master.
When the power goes up, I then of course see the temp jump from 50C to 70C, which is no good if I'm evaluating cooling.
What I don't understand is:
1. Why when frequency and CPU load have both been at 100% for 6 minutes does the power suddenly jump?
2. How can I stop this happening (preferably temporarily in software)?
Here's the graph - you can see the jump at 02:00 from the end:
